Alex Bennée d4f6e58fcb tests/tcg: split cris tests into bare and libc directories
Bare tests are standalone assembly tests that don't require linking to
any libc and hence can be built with kernel only compilers. The libc
tests need a compiler capable of building properly linked userspace
binaries. As we don't have such a cross compiler at the moment we
won't be building those tests.
